Pharrell Lanscilo Williams (; born April 5, 1973), often known mononymously as Pharrell, is an American musician. He first became known as one half of the music production duo the Neptunes, which he formed with Chad Hugo in 1992. Fifteen of their productions have peaked within the top ten of the Billboard Hot 100, which includes four songs that peaked atop the chart. The two also formed the alternative band N.E.R.D. with drummer Shay Haley in 1999, for which Williams served as lead vocalist. He has been considered one of the most influential music producers of the 21st century for his impact on popular music.

He co-founded the record label Star Trak Entertainment with Hugo in 2001, as an imprint of Arista Records. Williams' 2003 debut single, "Frontin'" (featuring Jay-Z), peaked at number five on the Billboard Hot 100. He then signed with Virgin and Interscope Records to release his debut studio album, In My Mind (2006), which peaked at number three on the Billboard 200 despite mixed critical reception. Williams produced and guest performed alongside T.I. on Star Trak signee Robin Thicke's 2013 single "Blurred Lines", which peaked atop the Billboard Hot 100 and received diamond certification by the Recording Industry Association of America (RIAA). That same year, his guest appearance alongside Nile Rodgers on Daft Punk's single "Get Lucky" peaked at number two on the chart and won Record of the Year and Best Pop Duo/Group Performance at the 56th Annual Grammy Awards. Williams' 2013 single, "Happy"—released for the soundtrack to the animated film Despicable Me 2—became his second song to peak atop the chart that same year. It also served as lead single for his second album, Girl (2014), which peaked at number two on the Billboard 200 and saw positive critical reception.

Williams has received numerous accolades and nominations. He has won 13 Grammy Awards, including three for Producer of the Year, Non-Classical (one as a member of the Neptunes). He is also a two-time Academy Award nominee: in 2014 for Best Original Song for "Happy"; and in 2017 for Best Picture as a producer of Hidden Figures. As sole proprietor, he founded the multi-disciplinary media company I Am Other in 2014, which acts as both a record label and creative umbrella for his other endeavors, including his fashion label and retailer, Billionaire Boys Club. He has served as Men's creative director for Louis Vuitton since 2023.
